Deficiency? Or could it be caused due to her being 3 weeks from harvest?

Little bit of nute burn. Nothing to worry about. Healthy plant overall.

Will do! Yeah I was giving an 1/8 of the nutes ( according to the fast buds website) but I decided to up them. Guess I over did it but ill be sure to follow your advice and water ph accordingly.

Thanks again!

Yeah, probably nute burn. Auto's are more sensitive to nutrients than Photo Periods so I will generally feed them about 50% strength of what the bottle says.

I usually stop using CalMag during flower, but lots of people do use it so I don't think that's a problem.

Definitely add in a plain watering every second or third watering, just make sure it is PH'd in the 6.5-7 range.

Looks like you are getting close to harvest time. At 1-2 weeks before harvest make sure to give her a good flush and then feed only PH'd water until harvest.

Have fun

Thanks bro it's my first auto. Forgive me for the lack of info I'm a newb but I'm feeding advanced nutrients base nutes the ph perfect stuff. I also used a little beastie bloomz my buddy gifted me. (Only used it 2 times so far)

Thanks for the advice tho! I will be sure to water ph accordingly this week.

Does calmag being given every watering during flower cause this? Because I have been giving her that since week 2 of flower.

As far as ppm goes I haven't invested In a meter just yet.

Hi, nice looking cola!

It's often hard to tell by looking at just one picture with no other information, so I'm make a lot of assumptions here.

I'm thinking that looks like just a touch of nutrient burn. I would back off on the nutrients a bit and add in a plain 6.5-7 PH'd watering every second or third watering from now on.

If the problem rapidly gets worse then it could be a lockout issue which you can solve with a good flush.

You caught the problem early, I think you will be fine. If the problems persist, let us know what you are feeding her and the PH and PPM readings would be helpful as well.

Good luck
